I am a number theorist interested in Galois representations and the Langlands program and related areas in representation theory and geometry. I am an NSF postdoctoral research fellow at the University of Toronto with mentor Florian Herzig. During the 2016-2017 academic year, I was a Member at the IAS. I received my PhD from the University of Chicago working with Matthew Emerton.

My CV is available pdf.
